Problem Login Failed With Installed Application

Feb 15, 2008



I have an application that uses an MDF file as a database. Debug mode of application on developing machine works fine.
I synchronize my project to my home computer so that I can work home too. (I use AllwaySync for synchronisation, it copies newer file from the old location overwriting the old ones).

I also have a setup project in my solution for that app.

When I create and install the application on my local computer everything works fine. But when I install it one a different computer and then run it, it cannot connect to database. The error occures while conencting to database saying:




Code Snippet
Unable to open the physical file "C:Program Files........VBDB.mdf". Operating system error 5: "5error not found)".
Unable to open the physical file "C:Program Files........VBDB_log.ldf". Operating system error 5: "5error not found)".
Cannot open user default database. Login failed.
Login failed for user 'EKAROMAEka''.
File activation failure. The physical file name "C:Program Files........VBDB_log.ldf" may be incorrect.





the second time I try run my application I get the following error (and all following tried where resulted in this error):



Code Snippet
Cannot open user default database. Login failed.
Login failed for user 'EKAROMAEka'.




These exceptions are caught by "try catch" when feeding data into DataGridView om my main form.

I have the sam username and password on my Home and Work computers.

I'm not very good at MSSQL security. I don't know how to solve this problem. I can't even understand wheather this is a security that's built in an MDF file or some kind of a Database server issue.

the connection string that I use for connecting to SQL Server is this:




Code Snippet
Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|VBDB.mdf;Integrated Security=True;Connect Timeout=30;User Instance=False







Thanks in advance.

SQL Security :: User Login Failed For Web Application

Nov 19, 2015

We have a Web application that requires user authentication.  We have a Login Page for user's to login and be authenticated.  We also manage the user accounts using SQL Server Membership Provider.  We created aLogin user in SQL Server and used this user's privileges to connect to SQL Server in our website's connection strings.  Example, in our Web.config file, the connection string is:

<connectionStrings>
  <addname="MyConnectionString"connectionString="Server=MYSERVERNAMESQLSERVER2012;Initial
Catalog=MyDatabase;User Id=TUser;Password=MyPassword"providerName="System.Data.SqlClient"/>
</connectionStrings>

The problem now is when a user logs in, it's throwing an error that TUser's password has already expired.  We did not enforce the password policy and expiration date for this user.  So, I'm wondering why it's giving me this error.

Login Failed For 'user' (Application Role)

Oct 16, 2006

I've created a database in SQL Express and I have a Windows form attempting to connect to it through SQL Authentication. Connection string:

private string connString = @"Data Source=.sqlexpress;Initial Catalog=SQLTestDatabase;User ID=SearchAppRole; Password=password;";

The role I have added to the database is an Application Role. It has been added to the Database permissions with Grant checked for "Select" and "Authenticate".

If I test this with query analyzer, it returns expected results (if I remove Grant from 'Select', it fails)

sp_setapprole 'SearchAppRole', 'password'

select * from recipe

If I edit my connection string (for testing purposes) to use the sa account, the application can connect and run the Select statement:

private string connString = @"Data Source=.sqlexpress;Initial Catalog=SQLTestDatabase;User ID=sa; Password=sa_password;";

However, I cannot get the application to successfully logon and run the select statement when using the user id and password of the Application Role. I get error:

System.Data.SqlClient.SqlException: Login failed for user 'SearchAppRole'. at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj


I can't find much information on Application Role...I just want one basic permission for the application as a whole. Any help is appreciated. Thanks.

Cannot Open Database XXXX Requested By Login. The Login Failed. Login Failed For User 'xxx'

Mar 18, 2007

hi,
 so i have a new box and I'm trying to get my websites and SQL Server 2005 Standard Edition working on it, but the pages give me the following error when I try to load them:
"Cannot Open Database "XXXX" requested by login.  The login failed.  Login failed for user 'xxx'"
Everything seems exactly the same settings and user-wise from my old box to my new one, but nevertheless everything I've tried gives me the same error.
I've tried creating new users in SQL Server and giving them appropriate permissions to my database.  I've even tried just using the built in 'sa' account.  Nothing seems to change the error, except when I give it the incorrect password then it just says 'login failed'
This leads me to believe that i'm successfully logging into the SQL Server, but it doesn't want to give me access to the database I'm requesting access too.  But "apparently" the account i'm using should have access to the database.  If nothing else the 'sa' account should, but that didn't work either.
I'm stumped.  Any ideas?

Login Failed For Trusted Connection Login Failed For User 'NT AUTHORITYANONYMOUS LOGON'

Mar 13, 2007

We have a SQL 2000 Active/Passive cluster running on Windows 2000. On one node, everything logs in fine (second node is powered off). I can use local authentication fine in OSQL (-E) and even see my connection in SQLEM current activity as [DomainUser] for the NT account which I am logged in as. Then I bring the second node online and initiate a failover. SQL Server starts but Cluster Admin cannot connect and starts throwing this Anonymous Logon error. I open a command prompt and try the same OSQL (-E) local login and sure enough it is also giving the Anonymous Logon connection user. I do not understand why the failover to a second node is causing the Trusted Connection Local authentication to switch to Anonymous instead of the [DomainUser] which I am using. Any help is appreciated. John.

SqlException (0x80131904): Cannot Open User Default Database. Login Failed. Login Failed For User 'xxxASPNET'

Jun 17, 2007

Hey Microsoft: this affects development that will eventually sell a lot of seats on SharePoint Server 2007. If you guys and gals can't straighten out this mess, you can't expect custom solutions with custom web parts. So pay attention for your own good. Yes, SPS 2007 is what this is all about. I've created simpe web parts and deployed them, same VS 2005, but I need local development and debugging for more complex stuff. I'm really disappointed that you have no solution for this problem.



I've seen other posts on this, but the result seems to be the same: if you fix it, it's by accident, not by design.



1. I created a blank ASP.NET web site

2. I added a web part manager

3. I added a web part zone



I get the error described above. I have no idea why SQL Server settings are so screwed up.



I've tried all the stuff in the other posts - security settings, command line installation, etc. None of those worked.



The default template(s) don't copy anything into App_Data, nor create an empty folder. I don't know why that is. I have other web sites working just fine, but they use remote SQL databases, or local ones I created, and didn't need profile management (no forms authentication, no web parts, no web zones).



I've also started out with a local database, using SQL Authentication, later moving it to a remote server, and never had any problems. The SQL Server developer edition and Express seem to work just fine. I can also debug stored procs when the .mdf is in App_Data. So the problem isn't one of connectivity.



What would cause the default screw-up? This would seem to point from all directions to a problem with Visual Studio (2005)? The installation is defalt - perhaps some extras included (copy local), but nothing unusual. AJAX for ASP.net is installed, but not used in the above "default web site" trial. Likewise Syncfusion's tools, which work fine on other developer workstations at this same location, all of which are from the same image (purchased at the same time & imaged). That web parts work on other boxes, running all the same management tools (anti-virus, remote sys admin/sms etc.) makes none of those suspect.



I think Microsoft needs to have a clean problem solution and publish it. SP1 certainly doesn't fix it. What's worse is the stupid, lame error message. "I can't open the default database". Well, what did you try? What do you think the default is? What settings are you using? Why is there no debugging information other than the usual worthless trace information showing it's all deep within the ProviderBase and SqlClient namespace code? How is that supposed to be helpful?



If anyone has anything solid, not guesses, I'd like to know.

Can An SQL EE Application Be Easily Installed Onto A Runtime Local Desktop?

Am I correct in assuming that installing a SQL EE application on to a local runtime desktop would require a lot of experienced user intervention to install the SQL to each local cpu? Can a SQL app be installed automatically w/o a user intervening?

SQL Server 2008 :: Login Failed For Login (DomainNameUserName) Due To Trigger Execution

Sep 23, 2015

All the logins with sysadmin role are locked out in one of the SQL server. Also in that instance Logon trigger is implemented which allows only certain users with Windows Authentication to logon.

This server is converted into single user mode by using command prompt. Now we are attempting to connect to SQLServer using command sqlcmd -S FTCPU3239 (since we do not have any other login) and create a new login with sysadmin role but are refused due to logon trigger. it says Login failed for login 'DomainNameUserName' due to trigger execution.

Hello.

I'm using Visual Web Developer, .NET Framework 2.0, ASP.NET 20., IIS 5.1. on Windows XP Pro SP2.

I have assigned every possible user i can think of full permissions to the web folder, all of the subfolders, and the database files. This includes Administrator, Administrator Groups, ASPNET user, IUSR_Machine, Interner guest account, Network Group, Network Service Group, Power Users Group, Users.

I'm logged on as administrator.

When i run the web service from within VWD, i get this error.

Cannot open database "eBayTrader" requested by the login. The login failed.
Login failed for user 'DHJC2R91ASPNET'.

Does anybody know how to resolve this problem ?

I have been working on it for days. I will gladly pay someone to work this out with me over the phone/email. I'll send you a check before we start.

Thanks,

Cannot Open Database TestDB Requested By The Login. The Login Failed.

Jun 2, 2006

I have created a new database within SQLServer Express 2005 and have an ASP page in IIS. Any time i attempt to access the database I get the following error:

[Microsoft][ODBC SQL Server Driver][SQL Server]Cannot open database "testDB" requested by the login. The login failed.

The ODBC connection that I have created works fine if connecting to the same table (literally three sample fields with two records) in an Access database.

The database connection that I am using is:

Set DatabaseConnection = Server.CreateObject("ADODB.Connection")
DatabaseConnection.Open "DSN=testDB;UID=EINSTEINAdministrator&pwd=password;DATABASE=testDB;APP=ASP Script"
Set rs = Server.CreateObject("ADODB.recordset")
SQLString = "SELECT * FROM testTable"
rs.Open SQLString, DatabaseConnection
if NOT rs.EOF then
Response.Write(rs("testField1") & " - " & rs("testField2"))
end if
rs.Close
DatabaseConnection.Close
Set DatabaseConnection = Nothing

EINSTEIN is the name of the server, rs = Recordset. I have tried changing to just Administrator instead of machinenameAdministrator with no success. I have got SQL Server Management Studio Express CTP, and can log in fine to SQL Server using EINSTEINAdministrator.

Please can anyone help!

"Make sure the application for the project type (.rptproj) is installed."

I have no idea why this message appears.

Is this a known problem/bug ? Anybody any idea how I can solve this ?

Many thanks in advance.

Login Failed For User - Token Based Server Access Validation Failed With Infrastructure Error

Sep 9, 2015

Many a times see the below error in SQL Error log.

Login failed for user 'NT AUTHORITYANONYMOUS LOGON'. Reason: Token-based server access validation failed with an infrastructure error. Check for previous errors. [CLIENT: ]

Is this something to do here?

Note: If I run the below statement I know that the SQL Error log entry will go off, but wanted to know the real significance of this error?

CREATE LOGIN [NT AUTHORITYANONYMOUS LOGON] FROM WINDOWS

Cannot Open Database Xx Requested By The Login. The Login Failed.

Jul 20, 2006

Hi,
we are running a webapplication, using IIS6, Windows 2003 64 bit in classic Asp.
In the asp pages we connect to our SQL server (SQL Server 2005 64bit,windows 2003 64 bit), mirrored on a third sql server (same software setup as the first sql server).

The mirroring is without witness.

This works perfectly but sometimes we get the following error :

Description: [Microsoft][SQL Native Client][SQL Server]Cannot open database
"OBJECTS" requested by the login. The login failed.

In the logs of sql, we see that the offending connection does not go the principal but to the mirror. Which would cause the problem of course..

The name of the database varies, and there is no consistent error. Most of the time there are no problems (95%), but sometimes we get these errors.

Connection from the asp to sql is done using ADO, using following driver in the connectionstring :

Driver="{SQL Native Client}"

Does anyone have an idea what could be the problem ?
We can of course increase timouts for the mirroring, but is this the solution ?
